Deputy Attorney General Rod Rosenstein told the White House two weeks ago there were ongoing issues that'd delay the security clearance of senior adviser Jared Kushner, The Washington Post reported.

Rosenstein didn't give any specific concerns related to President Donald Trump's son-in-law in the Feb. 9 call to White House counsel Don McGahn, the Post reported.

The heads-up came amid revelations that a number of Trump administration officials were working without final security clearances.

And for more than a year, Kushner has had access to some of the nation's most sensitive material while waiting for his background probe to be finished, the Post noted.

A week after Rosenstein's call, White House Chief of Staff John Kelly announced anyone without final clearance would no longer be able to look at the top-secret information — putting Kushner's access at risk as soon as Friday.

The Post reported a White House spokesman declined to comment, as did Kushner's lawyer, Abbe Lowell.

But in a statement to The Washington Post on Feb. 16, Lowell said he had been assured by officials there was nothing unusual about the delay in Kushner's security clearance and "no concerns were raised about Mr. Kushner's application."

Two unnamed sources said Rosenstein told McGahn the Justice Department had obtained important new information, suggesting it could be an obstacle to his clearance process, the Post reported.

A third unnamed source said Rosenstein didn't talk about the nature of the ongoing investigation, the Post reported.

Kushner's access top-secret information — without having final security clearance — has frustrated Kelly, according to the Post. But McGahn and Kelly decided to wait for the FBI to complete its background investigation.

Their wait-and-see ended last week, when Kelly issued a new policy that would block staff with interim clearances from receiving top-secret information as of Friday.
